PROBLEM TO BE SOLVED: To dry a treatment part in a short period of time by blowing hot air to the treatment part and vaporizing the moisture of the treatment part in a short period of time in dental treatment. SOLUTION: An instrument 8 communicates with a heating means 10 provided inside a unit main body (work table) 2 through an instrument hose 9. Since an air heating means for heating air is provided to the unit main body side, a large-sized heating means is used, and the air heated in the unit main body is jetted through the instrument hose 9 from the instrument 8. An air tube provided inside the instrument hose 9 is represented by 9a, and a heating wire provided inside the tube 9a is represented by 9a<SB>1</SB>. By preheating the air inside the instrument hose 9, the hot air is jetted almost simultaneously with the drive of the instrument 8 and dental treatment work is efficiently performed.
